What is glucosamine?

Glucosamine is one of the building blocks of cartilage. Cartilage covers and protects the ends of bones, allowing them to move smoothly against each other. Glucosamine has recently emerged as an alternative treatment option for patients with osteoarthritis. It assists in the production of lubricant and shock absorbing materials in joints, which are necessary for healthy joint function. Glucosamine also appears to have some anti-Inflammatory effect. Glucosamine comes in two forms – glucosamine sulfate and glucosamine hydrochloride.

What does the research say?

• Glucosamine hydrochloride:Studies suggest the hydrochloride form may not be as effective in relieving pain as glucosamine sulfate. There is limited evidence showing the effect of glucosamine hydrochloride on cartilage.
• Glucosamine sulfate:Opinion is divided about the effectiveness of glucosamine sulfate on pain. In the majority of studies, glucosamine improved pain from OA of the knee. There is some evidence that glucosamine sulfate can slow cartilage breakdown in the knee.

How long will it take to notice an effect?

You may need to take the supplements for four to six weeks before you notice any improvement.

How much should I take?

The recommended dose of glucosamine is 1500mg/day taken orally either as tablet or in powder formula.

At PHYSIO4ALL we recommend ChondroPlex by BioCeuticals which contains three key joint nutrients (glucosamine, chondroitin and MSM), which promote healthy joint tissue. It is recommended adults take 1 tablet, three times daily to get the recommended 1500mg of glucosamine
